Description
The Jandy Water Pressure Switch R0457000 is a factory-original safety component precision-engineered for Jandy LXi pool and spa heaters. Its job is to continuously verify that water flow through the heat exchanger meets the minimum threshold required for safe heater operation. The moment water pressure dips below acceptable levels, this switch immediately disables the burner to avert overheating and potential damage to internal parts. Built as a genuine Jandy OEM replacement, it provides an exact mechanical and electrical match for all LXi units, making it the trusted choice for maintaining your heater’s safety systems.
